Serial No. 573,420.

To all whom @'25 may concern Be it known that I, GEORGE GODDU, a citizenof the United States, residing at Winchester, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Fastener Supplying and Delivering Mechanism, of which the following description, in connection with the accompanying drawings, is a specifica- -tien, like reference characterslon the drawings indicating like parts in the several figures. A

This invention relates to a fastener sup plying and delivering mechanism for machines for inserting fasteners in tivo superimposed Vsheets ot material, such, for in- Stance, as the quarters of boots and shoes and more particularly to machines for setting lacing hooks or studs although the invention, in its various features, is not limited to setting this particular form of ,tastener. L

The invention is shown as applied to the machine for inserting fasteners, illustrated .y

limproved means for mounting the hopper,

for holding fasteners to be supplied to the setting dies, whereby it is readily removable to permit a change in hoppers when a change in the style of fastei'ierfusetl is desired, thus cbviating the necessity of emptying and refilling the hopper.

Another object of the invention is to provide an improved mechanism tor segregating fasteners from the mass in the hopper and delivering them singly to a, raeeu'ay' for delivery to the inserting devices.

With these objects in view that feature ot the invention which relates te the improved 4means for mounting the hopper to insure ready removability, contemplates the provision of a friction clutch on the hopper shaft between the fastener segregating devices within the hopper and their actuating means on the machine trame, means for disgating fasteners contemplates the provision of a picker plate having a plurality of fas-v tener-lifting arms,l and mechanism for imparting an intermittent rotary mation thereto which prevents overthrow of the picker arms and invariably places them, in succession, in proper position tc deliver their fas teners to the raceway.

Although t-heieat-ures of invention just described are in their illustrated embodiment applied to a machine for inserting fasteners simultaneously in two superimposed sheets of material, these features of the invention, as defined by the claims, are not limited in their application to this type 0f machine but are equally applicable to a machine for inserting fasteners in a'fsingle sheet of material.

The preferred embodiment of the invention is illustrated in the accompanying drawings, in which- I Figure lis a front elevation of the hook hopper, the cover plate being partly broken away to show the interior mechanism; F ig. 2 is a vertical section on the line 2--2 of Fig. l; Fig. 3 is a horizontal section on the line 3 3 of Fig. l; and Fig. a is a: detail, in elevation, et' the driving mechanism for the picker plates within the hopper.

In the embodiment of the invention illus-l trated in theI drawings, tivo raceways for delivering lacing hooks to the hooks'ett-ing mechanism are shown, each of which ccnsists of a plate 220 secured at its upper end to the upper end of the hopper sipapcrting `Bracket E which is 'secured to he main frame of the' machine. .is the hooks are delivered from the hopper and pass down the plates S220 by force of gravity, they are held upon said plates by guard plate'- Q24:

arranged at right angies to the plates Q20 and separated theretrcm a suilicient distance to form slots to receive the necks of the hooks. The guard plates 2=l are also secured at their upper ends to the bracket E.

The hopper for containing the lacing hooks is of such shape that two streams of described in detail. The raceway plates 220 abut against the hopper just inside of its side plates and opposite. slots (Fig. 3) within which the hook delivering picker plates 238 (Fig. 1) operate. These picker plates are of the usual well known construction and are .driven intermittently by a mechanism now to be described.

Each picker plate is provided with a hub 240 (Fig. 2) which is secured to a shaft 242 j ournaled at its outer end in a bearing in the front side plate 234 and having. atits innerend a disk 2.44 projecting through an opening in the rear side plate 234 and forme ing one member of a friction driving clutch. The other member of the friction clutch is formed by a second disk 246 (Figs. 2 and 4) which is secured centrally to a radially slotted wheel 248 mounted upon the hollow hub 250 of the disk 246 having a bearing in a casing Ycarried by the bracket D. llChe disks 244 and 246 forming the friction clutch are held in Contact by means of a pin 254 (Fig. 2), provided with a hand wheel 256 and threaded into they hopper shaft 242 after passing through the hollow shaft 250.. With this construction when the disks of the clutch are in engagement, the

hopper shaft 242 and hollow'shaft 250 form substantially one shaft which rotates in the journals. formed in the forward wall 234 of the hopper and the rear wall of the casing 252. The casing 252, below the radially slotted wheel 248, is provided with a short shaft 258l (Figs. 2 and 4) which carries at its forward end a crank arm 260 having a tooth 261 adapted to enter the slots of the wheel 248 in succession as the shaft 258 is rotated.- The wheel 248 is also provided with a succession of conca-vities around its periphery which are adapted to be engaged successively by .the convexly curved surface of a disk 259 on thel hub of the crank 260 and lock the shaft 242 against rotation during the time that the pin 261 is disengaged from the radial slots in the wheel 248 (see Fig. 4). This mechanism is similar to what is known as the Geneva stop motion but it 'is different therefrom in that the actuator 260 and the convexly curved locking surface formed on its hub are in different planes. This construction permits the convexly curved locking surface carried by the actuator to eX- tend angularly for more than 1800 and, therefore, to insure a rigid locking of the shaft 242 against rotation during-'the period of time that the pin 261 is disengaged from the radial slots of the wheel 248. Where the complemental curved locking surfaces are less than 180OL in angular extent, the locking action is overcome before the radially slotted wheel is again engaged by its actuator and, therefore, there is an opportunity forl the parts which are being held stationary, in this case the picker plates, to move and destroy their alinement with the raceways. The extended locking surface provided by the construction shown in Fig. 4 holds thel picker `arms successively at the ends of the raceways in a proper position' ,chine,' all as shown inthe co-pending application hereinbefore referred to. So long as the shaft 264- rotates the picker plates will be continuously supplying lacing hooks to the raceways.

As hereinbefore mentioned, it is desired at times to either change the size or style or possibly the color of lacing hook upon which the machine is to operate, and instead of resorting to the slow process of removing all the loose lacing hooks from the hopper which is in the machine and then re-supplying that hopper with other lacing hooks of the kind or color desired, in the present machine the hopper is so mounted that it can at such times be readily and quickly removed and another substituted therefor.

To this end the hopper is held to itssupport by means of bayonet joint and swing bolt and nut and slot connections, now to be described. Referring first to Figs. 1 and 3, the upper end of the bracket E has pivoted thereto a swinging bolt 280 which is adapted to enter a slot 282 formed in a lug (Fig. 2) projecting from the left hand lower quadrant of the hopper. After being swung in place in said slot, the hopper and bracket are drawn together by means of a nut 284 threaded on the bolt.

Referring now to Figs. 3 and 4, the rear wall of the hopper is provided with a series of, in the present instance three, L-shaped.

invasa() guided by the guideways so that they invav is free of the shaft 242 and the friction riably move beneathV the projecting. hooks 290 formed on the guideways, which act to hold the vhopper securely from --moving outwardly from the casing 252, This is in effect a bayonet joint and its advantages will be clear, as the fruideways 288 enable the hopper to instantly be pla-ced for its rotary movement into locked position. W'ith a hopper mounted in this manner, in order to remove it from the machine it is merely necessary to rst unscrew the pin 254 until it thus disengaged, and then swing the bolt 280 out of its engagement with the slot 282 in the lug on the hopper, and finally give the` hopper an angular bodily movement about the shaft 242 as an axis until the L -shaped lugs 286 are free of the hooks 4290. After these operations the hopper mayV be pulled forward from the bracket D and taken from the machine. A new hopper may be. qpickly placed -in operative .position by a reversal of the operations just described.'
